Walter and Willy and the False Note (Walter and Willy #5)

Bonnie Grubman grew up with a love of reading. As a child, she lived in an apartment with her family, pet turtles, and a parakeet. On hot summer nights, she would cool off on the fire escape with a flashlight and a big stack of books. Bonnie went to nursing school, but later decided to trade her nurse's hat for a classroom full of picture books. She was inspired by her students who found joy and curiosity in everything they saw. Because of these kids, and for all kids, she became a writer. Bonnie lives in Syosset, New York.
